       form_page - set and get form page number

SYNOPSIS
       #include <form.h>
       int set_current_field(FORM *form, FIELD *field);
       FIELD *current_field(const FORM *);
       int set_form_page(FORM *form, int n);
       int form_page(const FORM *form);
       int field_index(const FIELD *field);

DESCRIPTION
       The  function  set_current  field  sets the current field of the given form; current_field
       returns the current field of the given form.

       The function set_form_page sets the form's page number (goes to page n of the form).

       The function form_page returns the form's current page number.

       The function field_index returns the index of the field in the field array of the form  it
       is  connected  to.  It returns ERR if the argument is the null pointer or the field is not
       connected.
